I think that if you took out the panel that divided the sleeping and day areas then it might be ok. If you left it in then it may cause territory issues or make it easier for one or the other of them to hide and cause the bonding to take longer.
I have found that bonding is easier in spaces where there is nowhere for either of them to hide, so they have no option but just to get on with it.
You should also keep an eye on them while they are in there so if there is a fight you can get in there and split them up quick.
